Unable to send emails to Blueyonder or Ntlworld addresses

[Jaxtanner]

My Outlook account will no longer send emails to Blueyonder or Ntlworld addresses and I get the following message:

    Delay reason: H=mxin5.virginmedia.com [84.116.6.18]:

    SMTP error from remote mail server after RCPT TO:<............@ntlworld.com>:

    450 4.7.0 too long without DATA comma

Help!!!!!!

@Jaxtanner Probably connected with an issue that VM have acknowledged here:
